DUNKIRK, INDIAN GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 391,537, dated October 23, 1

Application filed December 1, 1887.

T0 on whom it may concern:

Be it known that I, JOSEPH A. KLOEB, residing at Dunkirk, in the county of Jay and State of Indiana, have invented certain new and useful Improvements in Burners for Natural and Artificial Gas, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to burners for natural or artificial gas.

The invention consists in the construction and combination of parts, as hereinafter described.

The object of the invention is to produce a burner for heating purposes, in which a complete mixing .of the gas with atmospheric air will be had, and with which a very perfect combustion of gas will be maintained.

Figure 1 is a vertical central section of the improved burner and attachments. Fig. 2 is a bottom or inside view of the conical deflector, shown in Fig. l in section. Fig. 3 is a bottom or inside view of a quadrangular deflector. Fig. 4 is a longitudinal section of a quadrangular deflector.

A indicates the gas-supply pipe, which receives gas under pressure from any suitable source of supply. The gas passes through a reduced orifice at B, and has an upward tendency at that point. The casing G surrounds the mouth of the pipe A and incloses what I call the mixing-chamber D. This chamber D has air-inlet openings E through the casing at the lower part thereof. A pipe, F, leads upward from the interior of the chamber D. This pipe F engages the casing O by a screw-thread, G, and can be adjusted rela tively to the casing, so as to leave a greater or less space between the upper end of pipe A and the lower end of pipe F. The casing O is also vertically adjustable on the pipe A by means of screw threads H. The upper end of pipe F supports a deflector, I, which is held up by bracket K, so as to leave a little space between the top of the pipe F and the bottom of the deflector.

In operation the gas passes up from pipe A into the chamber D through the small orifice B. The upward movement of the gas causes Serial No. 256,691. (No model.)

an entrance of air through holes E into the chamber D, and from this chamber the mingled air and gas pass through the tube F and strike the bottom of the deflector I. The mingled air and gas are turned downward by this deflector, and when ignited will burn around the base of the deflector. The tube F extends up into the deflector, thus delivering the mixed air and gas atalevel above the lower edge of the deflector. The gas, being lighter than air, will fill the chamber formed by the downwardly-extending edges of the deflector before flowing out around the edges thereof. The bottom of the deflector, being open to the air, receives an additional supply of air, the amount being determined by the flow of gas.

The deflector may be generally conical, as at I in Figs. 1 and 2, or may be of rectangular or other form, with a flat top and depressed edges, as at I in Fig. 4. The deflector will generally be of thin metal, havinga bracket, K, attached at the inner surface, or lugs K may extend inwardly far enough to rest upon the top of the pipe, and thus support the deflector a little above the mouth of the pipe. In fact, many well-known mechanical devices maybe adopted in lieu of the bracket K, or as equivalents thereof.

The deflector may have openings in the top, as at M, and these openings be closed or opened at pleasure by the pivoted dampers N, which operate in the manner usual to such dampers. When the holes M are open or partly open, a part of the flame of the burning gas will pass up through the openings.

The air and gas are quite well mixed before coming against the deflector. The deflector soon becomes hot, and a very perfect combos tion is secured around the edges thereof, and as the combustion is complete the burner gives off very little smoke or noise.
